PUMP.

SPECIFICATION forming part of Letters Patent-No. 249,885, dated November22, 1881,

Application filed July 2, 1881. (Model) or figures of reference markedthereon, which form a part of this specification.

This invention relates to certain improvements in pumps; andit consistsin certain details of construction, which will be hereinafter more fullydescribed, and then pointed out in the claims.

In the accompanying drawings, Figure 1 shows a side elevation; Fig. 2,an enlarged sectional view of the pump-cylinder and connections. Fig. 3is also an enlarged view, partly in section, showing the manner ofconnecting the parts; and Fig. 4, a detail plan view of thefastening-lugs.

A represents the pump-cylinder, which is held between the coupling B,into which the discharge-pipe U is screwed, and the coupling D, whichreceives the suspending-rod, which may be solid, or it may be hollow toform a vacuum-chamber, E, which rod or pipe also passes loosely througha socket, b, formed in the coupling B, and is connected above to thebase-plate; or it ma yform part of the standard.

Between the upper coupling, B, and the cylinder A is a packing-ring, a,and between the lower coupling and the cylinder is a packing formed ofthe leather or other suitable material of which the valveV is made. Thisvalve differs from the style of valve usually employed in this style ofpump, inasmuch as it is provided with abeveled disk, 0, fitting on abeveled seat, (I, in the coupling D. This disk may be either madeseparately and attached by the bolt that holds the weight on thepackingleather, or this packing-valve may be made of a single piece ofrubber, leather, or other suitable material molded into shape.

The rod or pipe E screws into the coupling D, passes loosely through thesocket b of the l coupling B, and extends upward through the platform orbase-plate F, to which it is securely fastened by a set-screw, f, orother suitable fastening, thereby forming a support for the coupling D,and the inlet-pipe screwing into the bottom of said coupling. The upperend of the pipe or rod E also extends through thehandle-supportingcastin gor head-plate G, and iI s supplied with acap-nut,g, as represented in The discharge-tube 0 screws into thecoupling B and extends upward, and is fastened to the base-plate F inthe same manner as the rod or pipe E, its upper end, however, afterpassing through the head-plate G, being provided with a thread toscrewinto the union h, which is provided with aninternalright thread toreceive said discharge-tube, and with an external left thread to screwinto the lower end of the curved spout H. Short sections of pipes orrods I are screwed, one at each side,into the base-plate F, and havetheir upper ends fitted into sockets in the head-plate G, their upperends being screw-threaded and provided with nuts t'. By thisconstruction the pipes G E form two posts and the short sections I twoadditional posts atdifi'erent points for supportin g the head-plate Gr.

The parts are secured tightly together by turning the nuts t' of thesections I, so as to force the head-plate G upward against the .union hand the cap-nutg The two couplings B D are securely drawn together andagainst the ends of the cylinder A by bolts K, which pass looselythrough holes in the lugs k k of the lower coupling and lugs l l of theupperv coupling, and are provided with nuts m m at their upper ends. Thelugs l l are each provided with a side opening, Z, as shown in Fig. 4,and are also made with conical recesses to receive the conical faces ofthe fastening-nuts, so that by loosening the nuts the bolts can swingoutward through the opening 6 without entirely removing the nuts.

If preferred, the heads may be made conical instead of the nuts.Instead, however, of making the nuts or heads with conical faces, asdescribed, circular recesses may be made in the lugs llarge enough toreceive the entire lower surface of an ordinary nut.

When thefastening-bolts have been detached from the coupling B, asdescribed, the coupling B can be raised vertically with itspacking-cylinder L, to allow acce s to the interior of the pump forinspection or repairs, by loosening the set-screw and drawingthedischarge-pipe O upward,the socket or sleeve bof the coupling BSliding vertically on the suspending rod or pipe E during thisoperation, so as to act as a guide for insuring the "ertical movement ofthe coupling. Then the upper coupling is raised to the desired lengthitcan be held in position by tightening the set-screwf. The setscrewsff,when screwed into place after the bolts it have been tightened, relievethese bolts of all strain. By these means the cylinder, piston, valve,and packing-rings can each be removed for inspection or renewal withoutraising the whole pump above the platform, leaving the inlet-pipe, thelower coupling, and the suspending pipe or rod in their normal positionin the well.

By making the valve and seat of the shape shown and described a tighterfit is obtained, and the beveled seat prevents the lodgment of anyforeign material.

What we claim as new is- 1. In a pump having its cylinder suspendedbelow the base-plate, a suction-pipe suspended independently of saidcylinder and the discharge-pipe coupling, whereby the cylinder may beremoved without disturbing the suction-pipe, substantially as described.

2. In a pump having its cylinder suspended below the base-plate, asuction-pipe suspended below said base-plate by a rod connected directlyto the base-plate, and connected to the suction-pipe by a suitablecoupling, whereby the suction-pipe is properly supported when thecylinder is removed, substantially as specified.

3. A pu-mp having its suction-pipe united bya coupling directly with abranch pipe extending above the cylinder to form a combinedvacuum-chamber and suspending-rod, and opening directly into thecoupling, substantially as specified.

4. In a pump, the combination of the coupling D, carrying thesuction-tube, with the suspending-rod E, whereby the suction-tube may beheld in its normal position when the cylinder is removed, substantiallyas described.

5. In a pump, the coupling B, provided with an opening for thedischarge-tube C, and the coupling D, having an openingfor the suspending-rod E,in combination with said tube 0, rod E, the cylinder A, andsuitable fastening devices, substantially as described.

6. In a pump, the couplings B D, one of which has slots provided withrecesses, in combination with the cylinder A, and bolts having heads ornuts fitting into the recesses in the coupling, substantially as and forthe purpose set forth.

7. In a pnmp,the couplings B D, in combination with the cylinder A. thedischarge-tube 0, rod E, and bolts K, substantially as described.

8. In a pump, the couplings B D, having slots provided with recesses, incombination with the cylinder A, discharge-tube G, rod E, and boltshaving nuts or heads fitting into recesses, substantially as described.

9. In a pump, the combination of the baseplate F, provided withset-screws ff, with the couplings B D, dischargepipe G, and thesuspending pipe or rod E, substantially as described.

10. In a pump, the combination of the baseplate F, provided withset-screwsff, with the head-plate G, union h, cap-nut g, sections I, andnuts 1' on said sections I, substantially as described.

11. Ina pump, the coupling B, provided with an opening for receiving theupper cylinder, a lower opening concentric with the upper one forreceiving the lower cylinder, an extension for receiving thedischarge-pipe, and a guidingsocket, I), substantially as described.

In testimony whereof we atfix our signatures in presence of twowitnesses.
